Mac Rumors has discovered that the latest iPhone OS update contains evidence that points towards a new iPhone.
The code strings which can be found in iPhone OS version 2.2.1 designate an iPhone with the model number “iPhone2,1″. For reference the current iPhone 3G is model “iPhone1,2″ while the original iPhone is “iPhone1,1″.
